This fascinating new documentary finally restores footage of Big Edie and Little Edie Beale of GREY GARDENS that was thought lost for decades. In 1972, artist Peter Beard initiated a film project with Lee Radziwill (Jackie Onassis’ sister) about her relatives, the Beales, for which they hired filmmakers David and Albert Maysles to help out. Though this project never did see the light of day, the Maysles returned of their own accord to the same material to make their now-legendary film. The footage in THAT SUMMER focuses on Big and Little Edie before the clean-up that rendered Grey Gardens more livable, as they interact with Radziwill and reflect upon their past. It also focuses on Beard and his family of friends, including Andy Warhol, Mick Jagger and Truman Capote, who formed an enormously influential and vibrant creative community in Montauk, Long Island (NY) in the 1970s. “You've never seen the mother-daughter duo quite as they're revealed in THAT SUMMER. Swedish director Göran Hugo Olsson, whose masterful touch with found footage made THE BLACK POWER MIX TAPE 1967–1975 a potent historical chronicle, again delves into the vaults with engrossing results.” - Sheri Linden, The Hollywood Reporter.
